Embodiment one

Preceding shock mitigation system 1 provided in this embodiment is used for model car 2.

Referring to shown in Fig. 1-Figure 15, the preceding shock mitigation system 1, including left damper 10, right damper 11 and rotating bracket 12；

The bottom end of left damper 10 and the bottom end of right damper 11 are for hinged with the preceding bridge 20 of model car 2 respectively；A left side subtracts The elastic component of device 10 and right damper 11 by compression thereon is shaken, and shock loading is absorbed by the deformation of elastic component；

Rotating bracket 12 includes rack body 120, left connecting shaft 121, pivotal axis 122 and right connecting shaft 123, along bracket sheet The direction from left to right of body 120, left connecting shaft 121, pivotal axis 122 and right connecting shaft 123 are successively set on rack body 120 On, pivotal axis 122 is used for the preceding bridge subframe 21 of model car 2 hingedly, and left connecting shaft 121 and left damper 10 are hinged, right Connecting shaft 123 and right damper 11 are hinged.

Specifically, when the near front wheel (not shown) of model car 2 encounters the case where road surface is protruded, left damper 10 Elastic component is compressed, while left damper 10 drives rotating bracket 12 to rotate around pivotal axis 122, thus 12 band of rotating bracket Moving right damper 11, deformation occurs.Similarly it is found that when the off-front wheel (not shown) of model car 2 encounters the case where road surface is protruded When, the elastic component of left damper 10 can also deformation occurs with the deformation of the elastic component of right damper 11.

That is, the preceding shock mitigation system 1 in the present embodiment, when the near front wheel of model car 2 receives the impact from road surface When load, by the way that left damper 10 and right damper 11 are connected between rotation, the near front wheel and the right side when model car 2 When either side in front-wheel is by shock loading from road surface, the elastic component of left damper 10 and right damper 11 can all be generated Deformation, efficiently uses the compression travel of left damper 10 and right damper 11, so that shock mitigation system 1 is for scabland before improving The adaptability and absorbability of shock loading caused by shape.

In the optinal plan of the present embodiment, the distance between bottom end of the bottom end of left damper 10 and right damper 11 is the The distance between top of one distance, top of left damper 10 and right damper 11 is second distance, and first distance is greater than the Two distances；It is greater than second distance by limiting first distance, advantageously reduces the impact force of the left and right directions of bridge 20 before being applied to. Specifically, i.e., the distance between left rotary shaft and right spindle are second distance.

Along the left and right directions of preceding shock mitigation system 1, the section of rack body 120 is V-shaped, left connecting shaft 121 and right connecting shaft 123 are separately positioned on the both ends of rack body 120, and the middle part of rack body 120 is arranged in pivotal axis 122.By by bracket sheet The cross sectional shape of body 120 is set as V-arrangement or approximate V-arrangement, is conducive to the compression travel for improving left damper 10 and right damper 11 Utilization rate, avoid left damper 10 excessive relative to the rotational angle of preceding bridge 20 with right damper 11.

Embodiment two

Embodiment two provides a kind of model car 2, which includes the preceding shock mitigation system 1 in embodiment one, embodiment The technical characteristic of preceding shock mitigation system 1 disclosed in one is also applied for the embodiment, the published preceding shock mitigation system 1 of embodiment one Technical characteristic is not repeated to describe.
